  • Field Details

    • UNREALIZED

      static final int UNREALIZED
      A Player in the UNREALIZED state has been instantiated, but does not yet know anything about its media. When a media Player is first created, its unrealized.
      See Also:

    • REALIZING

      static final int REALIZING
      When realize is called, a Player moves from the UNREALIZED state into the REALIZING state. A realizing player is in the process of determining its resource requirements. During realization, a Player acquires the resources that it only needs to acquire once. These might include rendering resources other than exclusive-use resources. (Exclusive-use resources are limited resources such as particular hardware devices that can only be used by one Player at a time; such resources are qcquired during PREFETCHING.) A realizing Player often downlaods assets over the net.
      See Also:

    • REALIZED

      static final int REALIZED
      When a Player finishes realizing it moves into the REALIZED state. A realized Player knows what resoures it needs and information about the type of media it is to present. Because a realized Player knows how to render its data, it can provide visual components and controls. Its connections to other objects in the system are in place, but it does noct own any resources that would prevent another Player from starting.
      See Also:

    • PREFETCHING

      static final int PREFETCHING
      When prefetch is called, a Player moves from the Realized state into the Prefetching state. A Prefetching Player is preparing to present its media. During this phase, the Player preloads its media data, obtains exclusive-use resources, and anything else it needs to do to prepare itself to play. Prefetching might have to recur if a Player's media presentation is repositioned, or if a change in the Player's rate requires that additional buffers be acquired or alternate processing take place.
      See Also:

    • PREFETCHED

      static final int PREFETCHED
      When a Player finishes Prefetching, it moves into the Prefetched state. A Prefetched Player is ready to be started; it is as ready to play as it can be without actually being Started.
      See Also:

    • STARTED

      static final int STARTED
      Calling start puts a Player into the Started state. A Started Player's time-base time and media time are mapped and its clock is running, though the Player might be waiting for a particular time to begin presenting its media data.
      See Also:

    • CLOSED

      static final int CLOSED
      A player with this state has been explicitly closed or has encountered an error and can not be used any more.
